Generally, when people choose a freezer, they always need to consider various factors. From the appearance point of view, the freezers on the market are similar, but the refrigeration systems inside may be very different. The quality of the refrigeration system directly determines the use effect and long service life of the refrigerator, so the refrigeration system is the most important core part of the refrigerator, which is composed of many parts.
The refrigeration system in the freezer is a unit composed of compressors, evaporators, condensers, and capillary tubes. In this refrigeration system, the compressor is a starting device. When the temperature in the cabinet drops to meet the set requirements, it will start It will automatically stop working, and it will automatically run again when the temperature rises. The compressor is equivalent to the heart of the freezer. Its function is to increase the pressure and temperature of the refrigerant by compressing the refrigerant, so as to promote the circulation of the refrigerant in the system.
The capillary in the freezer system is the throttling and pressure-reducing device of the refrigeration system. It has two main functions: one is to maintain a certain pressure difference between the evaporator and the condenser during the operation of the refrigeration system, so that the refrigerator can be refrigerated. The refrigerant evaporates and absorbs heat under the specified low pressure in the evaporator, so that the gaseous refrigerant in the condenser condenses and releases heat under a certain high pressure: another function is to control the flow of the refrigerant to keep the evaporator at a reasonable temperature. In order to realize the safe and economical operation of the refrigerator. The material of the capillary is preferably copper.
The evaporator is another core component in the refrigeration system. The evaporator is a metal circular structure with a smooth inner wall. The function of the evaporator in the freezer is to achieve the cooling effect by evaporating the low-temperature and low-pressure refrigerant liquid sent by the capillary tube into the refrigerant saturated vapor after absorbing the heat of the food in the box. The evaporator is a very important part of the four major components of refrigeration. It is mainly composed of two parts: a heating chamber and an evaporation chamber.
